Software Test Design Techniques

To write the Test Cases in more effective and efficient way, we are having the below main Software Test Design Techniques:

  1. Boundary Value Analysis (BVA)
  2. Equivalence Class Partition (ECP) 
  3. Error Guessing
  4. State Transition Diagrams
  5. Decision Table Testing

 

Boundary Value Analysis (BVA):

Whenever we are having a range like 1 to 10000 or 1 to 1000000 or 100000 to 10000000 etc. then it is not possible to perform the exhaustive testing, so at that time we need to use the Boundary Value Analysis Technique.

  • Divide the range of multiple boundaries like:

Min – 1, Min, Min + 1, Middle, Max – 1, Max, Max + 1.

  • To perform the Positive testing, Test the field with the boundaries like:

Min, Min + 1, Middle, Max – 1, Max.

So the application should accept these boundaries.

  • To perform the Negative testing, Test the application with the boundaries like:

Min – 1 and Max + 1.

So the application should not accept these boundaries.

  • If it is working as expected, then we can conclude that the field is accepting only the range.

For example: there is any field of product quantity with the range of 1 to 1000.
